20 points Save Answer QUESTION 9 While screening newborns for hemoglobin mutations, you identify a mutation resulting in a change of amino acid glutamate to leucine. Do you expect this change to result in a form of sickle cell disease? from valine leucine wale walio This mutation is quite concerning, because leucine is non-polar like valine (the usual mutation in sickle cell anemia). and thus may form similar hydrophobic interactions This mutation is not concerning, because leucine is polar like glutamate, and thus won't form hydrophobic interactions There is no way of knowing, because we don't yet have a good understanding of polar and amino acids non-polar characteristics of It doesn't matter which amino acids are changed; mutation QUESTION 10 Save Answer a toxin that inhibits glycolysis would only eukaryotes all non photosynthetic life forms We forms from all three domains of

Answer 1

& In sickel Cell Anemia at Position & Glutamate is replaced by Valine. Valine is a non-polar amino acid wherease Glutamate is a polar camino acid. while screening newborns for Hb mutations, a mutation is identified in which amino acid 6 change from Glutamate to leucine. Because leucine is also Non- polar amino acid like Valine so, This mutation is duite concerning, and this may form similar Hydrophobic interactions. so option (a) is correct. 16 A toxin that inhibit Glycolysis would effect life forms from all three domains of life. option (a) is incorrect because Glycolysis happened in prokaryotes also not only in eukaryotes option (6) is also incorrect because it affect both Plattosynthetic and non- photosynthetic life from option (c) is correct because all life from depends on Glycolysis for primary Energy source. Lactose can also be used in prokaryotes by Glycolysis is the primary one. option (d) is also incorrect because Glycolysis occur in both nerobic & acrobic life forms.
